Abstract
Oxalate and silica are considered antinutrients. Large quantities of oxalate and silica in plants can interfere with the uptake of essential minerals in ruminants. Therefore, the aim of this study was to compare the total silica and oxalate contents of seven varieties of Napier grass to find out which is best for cultivation. Taiwan, Zanzibar, Pakchong, Purple, Kobe, Indian, and Dwarf Napier grass were grown in a completely randomized design with three replications to determine their soluble oxalate, total oxalate, and silica contents. Plants were harvested at two months of plant maturity. Whole plant of the Dwarf Napier grass contained significantly higher soluble oxalate content than tall varieties. Total oxalate content in whole plant differed significantly among varieties. Dwarf showed the highest total oxalate content (3.23% dry matter (DM)) followed by Kobe (2.61%), Zanzibar (2.60%), Purple (2.44%), Taiwan (2.43%), Indian (2.15%), and Pakchong (1.95%). Regardless of variety, leaf tissue contained significantly higher soluble oxalate and total oxalate than stem tissue. There were no differences in silica content among them. In conclusion, the tall varieties could produce lower levels of soluble oxalate than the Dwarf variety, whereas silica content might not vary among them.Keywords: botanical fractions, mineral bioavailability, ruminant

Abstract
AIM To differentiate between infectious and non-infectious diseases occurring in immunocompromised patients without acquired immunodeficiency syndrome (AIDS) using high-resolution computed tomography (HRCT). MATERIALS AND METHODS HRCT images of 555 patients with chest complications were reviewed retrospectively. Infectious diseases (n=341) included bacterial pneumonia (n=123), fungal infection (n=80), septic emboli (n=11), tuberculosis (n=15), pneumocystis pneumonia (n=101), and cytomegalovirus pneumonia (n=11), while non-infectious diseases (n=214) included drug toxicity (n=84), infiltration of underlying diseases (n=83), idiopathic pneumonia syndrome (n=34), diffuse alveolar haemorrhage (n=8), and pulmonary oedema (n=5). Lung parenchymal abnormalities were compared between the two groups using the χ2 test and multiple logistic regression analysis. RESULTS The χ2 test results showed significant differences in many HRCT findings between the two groups. Multiple logistic regression analysis results indicated the presence of nodules with a halo and the absence of interlobular septal (ILS) thickening were the significant indicators that could differentiate infectious from non-infectious diseases. ILS thickening was generally less frequent among most infectious diseases and more frequent among most non-infectious diseases, with a good odds ratio (7.887, p<0.001). The sensitivity and accuracy for infectious diseases in the absence of ILS thickening were better (70% and 73%, respectively) than those of nodules with a halo (19% and 48%, respectively), while the specificity in the nodules with a halo was better (93%) than that of ILS thickening (78%). CONCLUSIONS The presence of nodules with a halo or the absence of ILS thickening tends to suggest infectious disease. Specifically, ILS thickening seems to be a more reliable indicator.

Abstract
Because ofboth the indolent and aggressive nature ofprostate cancers, it is not easy to select the best treatment for patients receiving home medical care who already have many diseases. Since the growth ofprostate cancer is generally slow and all treatments adversely affect the quality of life to some degree, conservative treatment may well be the best option for these patients with prostate cancer. However, it is also true that we often encounter home medical care patients with a locally advanced cancer who had symptoms such as difficulty to urine, macrohematuria and/or lumbago. Such patients need to be diagnosed soon and treated with mainly hormonal therapy after consultation with the specialist. Thus, after a careful evaluation ofthe nature ofthe cancer and comorbidity, we need to provide the best option ofdiagnosis and treatment for home medical care patients to maintain their quality of life.

Abstract
PURPOSE The endocrine therapy is effective for patients with advanced prostate cancer, but the disease eventually becomes refractory to treatment. The aim of this study was to investigate prognostic factors and to develop a risk stratification model for survival in patients with advanced prostate cancer undergoing endocrine therapy. MATERIALS AND METHODS This study included 197 patients with stage IV prostate cancer who were treated with endocrine therapy as primary treatment at Tokyo Medical University, Tokyo, Japan, between January 1999 and November 2012. Prognostic values including baseline clinical laboratory values before endocrine therapy for stage IV prostate cancer were examined. Patients (n = 30) who were not followed or for whom data were unavailable or who were treated with radiotherapy were excluded from the study. Excluding these patients, we retrospectively analyzed 167 patients who were treated with endocrine therapy as the primary treatment. Disease-specific survival (DSS) was evaluated using the Kaplan-Meier method, and prognostic factors were identified using the Cox proportional hazard model analysis. RESULTS In univariate analyses, patients with a performance status (PS) ? 2, platelet count ? 3.0× 105 µ/L, prostate specific antigen (PSA) > 50 ng/mL, alkaline phosphatase (ALP) > 350 U/L, lactate dehydrogenase (LDH) > 240 IU/L, and Gleason score (GS) ? 8, hemoglobin (Hb) < 12 g/dL, extent of disease (EOD) ? 3 and poorly differentiated adenocarcinoma showed significantly lower DSS than their respective counterparts. Neutrophil-to-Lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and white blood cell (WBC) count were not significantly associated with DSS. In a multivariate Cox proportional hazard model, PS and platelet count were independent prognostic factors. Based on the hazard rate (HR) calculated by the following formula: HR = exp (0.82 × PS + 1.38 × platelet count) patients were stratified into 3 risk groups. The differences in DSS rates among the 3 groups were statistically significant. CONCLUSION These results suggest that PS and platelet count are independent prognostic factors and that a combination of these factors can be used to stratify metastatic prostate cancer patients treated with endocrine therapy according to their DSS risk.

Abstract
BACKGROUND The aim of this study was to study the prognostic significance of tertiary Gleason grade (TGG) 5 in patients with clinically localized prostate cancer treated with robot-assisted radical prostatectomy (RARP). METHODS A total of 600 Japanese patients who underwent RARP for clinical stage T1-3N0M0 prostate cancer were evaluated. TGG5 was evaluated according to the International Society of Urological Pathology criterion. Cox hazard regression was used to evaluate the prognostic significance of prostate-specific antigen and pathological features in RARP specimens. RESULTS Of the 600 RARP specimens, 92 (15%) had TGG5. TGG5 component was found in 30 (10%) of 287 cases with Gleason score (GS) 3 + 4, 55 (37%) of 149 cases with GS 4 + 3 and 7 (17%) of 40 cases with GS 4 + 4. There were no significant differences in pathological stage and surgical margin status between GS 3 + 4 with and without TGG5, as well as between GS 4 + 4 with and without TGG5. Of the 600 patients, 92 (15%) patients had biochemical recurrence (BCR) after surgery, with a median follow-up period of 42 (3-104) months. There were no differences in 5-year BCR-free survival rates between patients with GS 3 + 4 with and without TGG5 (92 vs. 100%, P = 0.16), as well as between patients with GS 4 + 3 with and without TGG5 (79 vs. 71%, P = 0.30). Similarly, there were no differences in 3-year BCRFS rates between patients with GS 4 + 4 with and without TGG5 (80 vs. 71%, P = 0.38). CONCLUSIONS In our population, the presence of TGG5 in RARP specimens had no strong impact on pathological and prognostic outcomes.

Abstract
Human kallikrein peptidase 2 (hK2) is a prostate specific enzyme whose expression is governed by the androgen receptor (AR). AR is the central oncogenic driver of prostate cancer (PCa) and is also a key regulator of DNA repair in cancer. We report an innovative therapeutic strategy that exploits the hormone-DNA repair circuit to enable molecularly-specific alpha particle irradiation of PCa. Alpha-particle irradiation of PCa is prompted by molecularly specific-targeting and internalization of the humanized monoclonal antibody hu11B6 targeting hK2 and further accelerated by inherent DNA-repair that up-regulate hK2 (KLK2) expression in vivo. hu11B6 demonstrates exquisite targeting specificity for KLK2. A single administration of actinium-225 labeled hu11B6 eradicates disease and significantly prolongs survival in animal models. DNA damage arising from alpha particle irradiation induces AR and subsequently KLK2, generating a unique feed-forward mechanism, which increases binding of hu11B6. Imaging data in nonhuman primates support the possibility of utilizing hu11B6 in man.

Abstract
OBJECTIVE To clarify the impact of prostate-specific antigen screening on surgical outcomes of prostate cancer. METHODS Patients who underwent radical prostatectomy were divided into two groups according to prostate-specific antigen testing opportunity (group 1, prostate-specific antigen screening; group 2, non-prostate-specific antigen screening). Perioperative clinical characteristics were compared using the Wilcoxon rank-sum and χ2 -tests. Cox proportional hazards models were used to identify independent predictors of postoperative biochemical recurrence-free survival. RESULTS In total, 798 patients (63.2%) and 464 patients (36.8%) were categorized into groups 1 and 2, respectively. Group 2 patients were more likely to have a higher prostate-specific antigen level and age at diagnosis and larger prostate volume. Clinical T stage, percentage of positive cores and pathological Gleason score did not differ between the groups. The 5-year biochemical recurrence-free survival rate was 83.9% for group 1 and 71.0% for group 2 (P < 0.001). On multivariate analysis, prostate-specific antigen testing opportunity (hazard ratio 2.530; P < 0.001) was an independent predictive factor for biochemical recurrence after surgery, as well as pathological T stage, pathological Gleason score, positive surgical margin and lymphovascular invasion. Additional analyses showed that prostate-specific antigen screening had a greater impact on biochemical recurrence in a younger patients, patients with a high prostate-specific antigen level, large prostate volume and D'Amico high risk, and patients meeting the exclusion criteria of the Prostate Cancer Research International Active Surveillance study. CONCLUSIONS Detection by screening results in favorable outcomes after surgery. Prostate-specific antigen screening might contribute to reducing biochemical recurrence in patients with localized prostate cancer.

Abstract
Purpose To investigate the impact of the time interval (TI) between prostate biopsy and robot-assisted radical prostatectomy (RARP) on the risk of biochemical recurrence (BCR). Methods We retrospectively reviewed the medical records of 793 consecutive patients who were treated with RARP at our institution. Patients were divided into three groups, according to TI, to compare BCR-free survival (BCRFS) rates: Group 1 (n = 196), TI < 3 months; Group 2 (n = 513), 3 ≤ TI < 6 months; Group 3 (n = 84), TI ≥ 6 months. Eighty-three patients with TI ≥ 6 months were matched with an equal number of patients with TI < 6 months based on propensity scores by using four preoperative factors: prostate-specific antigen (PSA), primary (pGS) and secondary (sGS) Gleason score and positive prostate biopsy. Results The 5-year BCRFS rates for TI Groups 1, 2, and 3 were 76%, 80.7% and 82.6% (P = 0.99), respectively. The multivariate analysis revealed that PSA, pGS, sGS and a positive prostate biopsy were independent preoperative risk factors for BCR. The propensity adjusted 5-year BCRFS for patients with TI ≥ 6 months was 84.0%. This was not worse than that of patients with TI < 6 months (71.0%, P = 0.18). Conclusions In our cohorts, a delay in the time from biopsy to RARP did not significantly affect recurrence. Therefore, hasty treatment decisions are unnecessary for at least 6 months after diagnosis of early prostate cancer.

Abstract
OBJECTIVE Urinary incontinence is one of the most bothersome adversities after robot-assisted radical prostatectomy (RARP). The aim of this study was to investigate the urinary continence recovery and the effect of various surgical techniques. MATERIALS AND METHODS We previously reported that posterior rhabdosphincter reconstruction and nerve-sparing were independent predictors of urinary continence recovery 1 month after catheter removal in 199 patients who underwent RARP. Retrospectively, we further reviewed those 199 patients for urinary continence recovery at 3 months or later after RARP. The relationships of urinary continence with perioperative findings, including surgical procedures, were evaluated at 3 to 12 months after RARP. The Fisher exact test and Mann-Whitney rank sum test were used for evaluating variables between the groups. Multivariate logistic regression analysis was performed to investigate the association between urinary continence and perioperative factors. RESULTS On univariate analyses, surgeon experience, lateral bladder neck preservation (BNP), anterior reconstruction, and posterior reconstruction were significantly associated with urinary continence recovery 3 months after RARP, but only lateral BNP was independently associated with urinary continence recovery in a multivariate analysis. Similarly, on univariate analyses, surgeon experience, lateral BNP, and posterior reconstruction were significantly associated with continence recovery at 6 months or later after surgery. However, multivariate analyses showed that only lateral BNP was significantly associated with urinary continence recovery 6 months or later after surgery. CONCLUSION Although the lateral BNP technique did not affect immediate urinary continence recovery, this procedure was significantly associated with continence recovery 3 months or later after RARP.

Abstract
This paper reports the preliminary results of a new in-situ three-dimensional (3D) imaging system for observing plastic deformation behavior in a transmission electron microscope (TEM) as a directly relevant development of the recently reported straining-and-tomography holder [Sato K et al. (2015) Development of a novel straining holder for transmission electron microscopy compatible with single tilt-axis electron tomography. Microsc. 64: 369-375]. We designed an integrated system using the holder and newly developed straining and image-acquisition software and then developed an experimental procedure for in-situ straining and time-resolved electron tomography (ET) data acquisition. The software for image acquisition and 3D visualization was developed based on the commercially available ET software TEMographyTM. We achieved time-resolved 3D visualization of nanometer-scale plastic deformation behavior in a Pb-Sn alloy sample, thus demonstrating the capability of this system for potential applications in materials science.

Abstract
Primary small-cell carcinoma arising from the bladder (SmCCB) is uncommon. It differs from urothelial carcinoma (UC), the most common type of bladder cancer, with respect to its cell of origin, biology, and prognosis. Biologically, prostatic SmCCB is much more aggressive than UC, and the prognosis for cases with distant metastasis is especially poor. We report here a case of primary SmCCB (cT3bN1M0) treated with radical cystectomy.

Abstract
OBJECTIVES To investigate the predictive values of perioperative factors and to develop a nomogram for intravesical recurrence after radical nephroureterectomy in patients with upper urinary tract urothelial carcinoma. METHODS A retrospective analysis of 144 patients who underwent radical nephroureterectomy from 1996 to 2014 was carried out. The actuarial probabilities of the intravesical recurrence-free survival rate were calculated using the Kaplan-Meier method. Prognostic indicators for intravesical recurrence were identified using competing-risks regression analyses. RESULTS Intravesical recurrence occurred in 63 patients during the follow-up period. The intravesical recurrence-free survival rates at 1, 3, and 5 years were 65.7%, 50.6% and 47.1%, respectively. In univariate analysis, the presence of gross hematuria (P = 0.028) and the preoperative serum creatinine level (P = 0.033) were significantly associated with intravesical recurrence. In multivariate analysis, the presence of gross hematuria (subdistribution hazard ratio 2.03, 95% CI 1.145-3.496; P = 0.013) and the preoperative serum creatinine level (subdistribution hazard ratio 3.15, 95% CI 1.161-3.534; P = 0.021) were independent predictors for intravesical recurrence after radical nephroureterectomy. Accordingly, a nomogram based on the model was developed. The concordance index of this model was 0.632. CONCLUSION The presence of gross hematuria and preoperative serum creatinine levels seem to be independent predictors for intravesical recurrence after radical nephroureterectomy. Our nomogram developed based on these factors might aid in appropriate patient selection for clinical trials of novel therapeutic interventions, including administration of intravesical chemotherapy.

Abstract
PURPOSE To identify preoperative factors correlated with postoperative early renal function in patients who had undergone radical cystectomy (RC) and intestinal urinary diversion. METHODS We retrospectively identified 201 consecutive bladder cancer patients without distant metastasis who had undergone RC at our institution between 2003 and 2012. The estimated glomerular filtration rate (eGFR) was calculated using the modified Chronic Kidney Disease Epidemiology equation before RC and 3 months following RC. Univariate and stepwise multiple linear regression analyses were applied to estimate postoperative renal function and to identify significant preoperative predictors of postoperative renal function. RESULTS Patients who had undergone intestinal urinary diversion and were available for the collection of follow-up data (n = 164) were eligible for the present study. Median preoperative and postoperative eGFRs were 69.7 (interquartile range [IQR] 56.3-78.0) and 70.7 (IQR 57.3-78.1), respectively. In univariate analyses, age, preoperative proteinuria, thickness of abdominal subcutaneous fat tissue (TSF), preoperative serum creatinine level, preoperative eGFR, and urinary diversion type were significantly associated with postoperative eGFR. In a stepwise multiple linear regression analysis, preoperative eGFR, age, and TSF were significant factors for predicting postoperative eGFR (p < 0.001, p = 0.02, and p = 0.046, respectively). The estimated postoperative eGFRs correlated well with the actual postoperative eGFRs (r = 0.65, p < 0.001). CONCLUSIONS Preoperative eGFR, age, and TSF were independent preoperative factors for determining postoperative renal function in patients who had undergone RC and intestinal urinary diversion. These results may be used for patient counseling before surgery, including the planning of perioperative chemotherapy administration.

Abstract
PURPOSE To investigate the prognostic significance of sarcopenia on long-term outcomes in patients with bladder cancer after radical cystectomy (RC). METHODS We retrospectively reviewed 136 patients undergoing RC for urothelial carcinoma at our institution. Prognostic impact of the preoperative clinical, laboratory, and radiologic parameters were evaluated by Cox proportional hazard model analyses, and a nomogram was developed to predict cancer-specific survival (CSS) after RC. RESULTS The mean follow-up was 46.7 months. Patients with sarcopenia had a significantly shorter CSS than those without sarcopenia. On univariate Cox analysis, clinical T stage, histology of transurethral resection of bladder tumor (TURBT) specimen, pretreatment hemoglobin, pretreatment neutrophil-to-lymphocyte ratio (NLR), pretreatment serum C-reactive protein level, pretreatment serum albumin level, presence of hydronephrosis, and presence of sarcopenia were associated with significantly worse CSS. On multivariate Cox stepwise analysis, sarcopenia (hazard rate [HR] = 2.3, p = 0.015), clinical T stage (cT4: HR = 5.3; p = 0.0096), presence of hydronephrosis (HR = 2.0; p = 0.033), histology of TURBT specimen (HR = 2.2, p = 0.044), and NLR (HR = 1.3; p = 0.0048) were significant independent predictors of an unfavorable prognosis Based on the results of the multivariate analysis, we developed a nomogram to predict 1-, 3-, and 5-year CSS after RC. CONCLUSIONS Sarcopenia, clinical T stage, presence of hydronephrosis, histology of TURBT specimen, and NLR are novel preoperative prognostic factors even after adjustment for other known preoperative predictors in patients undergoing RC for bladder cancer.

Abstract
BACKGROUND Neutropenia is a major adverse event of docetaxel-based chemotherapy. The present study was undertaken to evaluate the incidence of neutropenia and to develop a nomogram for predicting Grade 4 neutropenia during the first cycle of docetaxel-based chemotherapy in patients with castration-resistant prostate cancer (CRPC). PATIENTS AND METHODS This study included 112 patients with CRPC treated with docetaxel-based systemic chemotherapy. We evaluated the incidence and risk factors for Grade 4 neutropenia in the first cycle of chemotherapy. RESULTS Sixty-two of 112 patients (55.4%) developed Grade 4 neutropenia in the first cycle of docetaxel-based chemotherapy. There were significant differences in age, baseline white blood cell count, and baseline neutrophil count between patients with non-Grade 4 neutropenia and those with Grade 4 neutropenia in univariate analyses. The serum prostate-specific antigen level, hemoglobin level, creatinine, albumin, Eastern Cooperative Oncology Group performance status, metastatic sites, extent of disease, and history of external beam radiotherapy to the prostate were not significantly different between the 2 groups. Multivariate logistic regression analysis showed that age (odds ratio [OR], 1.08; P = .019) and baseline neutrophil counts (OR, 0.79; P = .045) were significant independent risk factors for severe neutropenia. A nomogram and a calibration plot on the basis of these results were developed from a multivariate logistic regression analysis to predict the probability of Grade 4 neutropenia. CONCLUSION Age and baseline neutrophil counts were significant independent risk factors for Grade 4 neutropenia. The nomogram to predict it provides useful information for the management of patients with CRPC treated with docetaxel chemotherapy.

Abstract
OBJECTIVE The estimated glomerular filtration rate is significantly decreased after nephroureterectomy. Deteriorating renal function likely affects the eligibility for cisplatin-based chemotherapy in patients with upper tract urothelial carcinoma. The present study was undertaken to identify preoperative factors for the prediction of postoperative renal function and develop a prediction model. METHODS Between June 1996 and January 2014, 110 patients who underwent radical nephroureterectomy at our institution were analyzed in this study. The estimated glomerular filtration rate was calculated using the Modification of Diet in Renal Disease study equation. Univariate linear regression analyses were performed to investigate the correlation between postoperative estimated glomerular filtration rate and preoperative variables. A stepwise multivariate linear regression analysis was performed to identify independent predictors of postoperative estimated glomerular filtration rate. RESULTS Comparison of preoperative and postoperative estimated glomerular filtration rate for each patient showed a median difference of 13.1 ml/min/1.73 m(2). The postoperative estimated glomerular filtration rate was significantly lower than the preoperative estimated glomerular filtration rate (P < 0.001). On univariate analysis, age and preoperative estimated glomerular filtration rate were significantly correlated with postoperative estimated glomerular filtration rate. On multivariate analysis, age, preoperative estimated glomerular filtration rate and the presence of hydronephrosis were independent predictive factors of postoperative estimated glomerular filtration rate. The predicted postoperative estimated glomerular filtration rate, which was calculated using these independent factors, showed a significant correlation with the observed postoperative estimated glomerular filtration rate (correlation coefficient = 0.7533). CONCLUSIONS Age, preoperative estimated glomerular filtration rate and the presence of hydronephrosis were independent predictors of postoperative estimated glomerular filtration rate in patients with upper tract urothelial carcinoma treated with radical nephroureterectomy. The predicted postoperative estimated glomerular filtration rate based on these factors may be useful for choosing alternative management strategies such as neoadjuvant chemotherapy for patients with upper tract urothelial carcinoma.

Abstract
INTRODUCTION This retrospective study was undertaken to evaluate the combined effect of immediate intravesical chemotherapy and subsequent bacillus Calmette-Guérin (BCG) therapy. METHODS The study population consisted of 207 intermediate- or high-risk patients with non-muscle invasive bladder cancer who underwent an induction course of BCG between 1993 and 2007. We introduced single immediate instillation of 50 mg epirubicin for all cases in 2004, and thus earlier cases could be considered as historical controls. The primary endpoint was recurrence-free survival (RFS). For cumulative analysis, we systematically reviewed studies indexed in databases. Including ours, the records of 856 patients from a total of 7 studies, including ours, were finally analyzed. RESULTS In our cohort, the 5-year RFS in patients who received the combination therapy was 66.2%, compared to 55.2% in the BCG alone group (p = 0.149). Multivariate analysis on tumour recurrence showed that patients with the combination therapy had a hazard ratio (HR) of 0.74 (p = 0.189). A subsequent literature review revealed that RFS rates in the combination groups were higher than those in the corresponding BCG alone groups in 4/7 studies (p = 0.02-0.15), and lower in 1 study (p = 0.51). We identified 5 studies which examined a HR for combination therapy, and performed a cumulative analysis. Adding a single chemo-instillation prior to BCG resulted in a significant reduction in tumour recurrence (summary HR 0.69, p = 0.010). CONCLUSIONS Our analysis suggested that the combination of single chemo-instillation with subsequent BCG therapy exhibited an additive effect against potential tumour recurrence.

Abstract
The ability to visualize and spare nerves during surgery is critical for avoiding chronic morbidity, pain, and loss of function. Visualization of such critical anatomic structures is even more challenging during minimal access procedures because the small incisions limit visibility. In this study, we focus on improving imaging of nerves through the use of a new small molecule fluorophore, GE3126, used in conjunction with our dual-mode (color and fluorescence) laparoscopic imaging instrument. GE3126 has higher aqueous solubility, improved pharmacokinetics, and reduced non-specific adipose tissue fluorescence compared to previous myelin-binding fluorophores. Dosing and kinetics were initially optimized in mice. A non-clinical modified Irwin study in rats, performed to assess the potential of GE3126 to induce nervous system injuries, showed the absence of major adverse reactions. Real-time intraoperative imaging was performed in a porcine model. Compared to white light imaging, nerve visibility was enhanced under fluorescence guidance, especially for small diameter nerves obscured by fascia, blood vessels, or adipose tissue. In the porcine model, nerve visualization was observed rapidly, within 5 to 10 minutes post-intravenous injection and the nerve fluorescence signal was maintained for up to 80 minutes. The use of GE3126, coupled with practical implementation of an imaging instrument may be an important step forward in preventing nerve damage in the operating room.

Abstract
OBJECTIVES To investigate Haralick texture analysis of prostate MRI for cancer detection and differentiating Gleason scores (GS). METHODS One hundred and forty-seven patients underwent T2- weighted (T2WI) and diffusion-weighted prostate MRI. Cancers ≥0.5 ml and non-cancerous peripheral (PZ) and transition (TZ) zone tissue were identified on T2WI and apparent diffusion coefficient (ADC) maps, using whole-mount pathology as reference. Texture features (Energy, Entropy, Correlation, Homogeneity, Inertia) were extracted and analysed using generalized estimating equations. RESULTS PZ cancers (n = 143) showed higher Entropy and Inertia and lower Energy, Correlation and Homogeneity compared to non-cancerous tissue on T2WI and ADC maps (p-values: <.0001-0.008). In TZ cancers (n = 43) we observed significant differences for all five texture features on the ADC map (all p-values: <.0001) and for Correlation (p = 0.041) and Inertia (p = 0.001) on T2WI. On ADC maps, GS was associated with higher Entropy (GS 6 vs. 7: p = 0.0225; 6 vs. >7: p = 0.0069) and lower Energy (GS 6 vs. 7: p = 0.0116, 6 vs. >7: p = 0.0039). ADC map Energy (p = 0.0102) and Entropy (p = 0.0019) were significantly different in GS ≤3 + 4 versus ≥4 + 3 cancers; ADC map Entropy remained significant after controlling for the median ADC (p = 0.0291). CONCLUSION Several Haralick-based texture features appear useful for prostate cancer detection and GS assessment. KEY POINTS • Several Haralick texture features may differentiate non-cancerous and cancerous prostate tissue. • Tumour Energy and Entropy on ADC maps correlate with Gleason score. • T2w-image-derived texture features are not associated with the Gleason score.

Abstract
We have developed a newly designed straining specimen holder for in situ transmission electron microscopy (TEM) compatible with high-angle single tilt-axis electron tomography. The holder can deform a TEM specimen under tensile stress with the strain rate between 1.5 × 10(-6) and 5.2 × 10(-3) s(-1). We have also confirmed that the maximum tilt angle of the specimen holder reaches ±60° with a rectangular shape aluminum specimen. The new specimen holder, termed as 'straining and tomography holder', will have wide range potential applications in materials science.

Abstract
OBJECTIVE To identify preoperative factors predicting Gleason score downgrading after radical prostatectomy (RP) in patients with biopsy Gleason score 3+4 prostate cancer and to determine if prediction of downgrading can identify potential candidates for active surveillance (AS). PATIENTS AND METHODS We identified 1317 patients with biopsy Gleason score 3+4 prostate cancers who underwent RP at the Memorial Sloan-Kettering Cancer Center between 2005 and 2013. Several preoperative and biopsy characteristics were evaluated by forward selection regression, and selected predictors of downgrading were analysed by multivariable logistic regression. Decision curve analysis was used to evaluate the clinical utility of the multivariate model. RESULTS Gleason score was downgraded after RP in 115 patients (9%). We developed a multivariable model using age, prostate-specific antigen density, percentage of positive cores with Gleason pattern 4 cancer out of all cores taken, and maximum percentage of cancer involvement within a positive core with Gleason pattern 4 cancer. The area under the curve for this model was 0.75 after 10-fold cross validation. However, decision curve analysis revealed that the model was not clinically helpful in identifying patients who will downgrade at RP for the purpose of reassigning them to AS. CONCLUSION While patients with pathological Gleason score 3 + 3 with tertiary Gleason pattern ≤4 at RP in patients with biopsy Gleason score 3 + 4 prostate cancer may be potential candidates for AS, decision curve analysis showed limited utility of our model to identify such men. Future study is needed to identify new predictors to help identify potential candidates for AS among patients with biopsy confirmed Gleason score 3 + 4 prostate cancer.

Abstract
OBJECTIVE To investigate the clinical implication of preoperative serum total cholesterol (TC) level in patients with clear cell renal cell carcinoma (RCC). METHODS The records of 364 patients with clear cell RCC who had undergone nephrectomy were retrospectively reviewed. The association among preoperative TC level, clinicopathologic factors, and oncological outcome in terms of cancer-specific survival (CSS) and recurrence-free survival period was analyzed by univariate and multivariate analyses. RESULTS As a continuous variable, lower serum TC level was found to be significantly associated with male sex, symptomatic tumor, advanced TNM stage, higher nuclear grade, microscopic venous invasion, poor Eastern Cooperative Oncology Group Performance Status, larger tumor size, elevated C-reactive protein level, and lower hemoglobin level. Univariate analysis showed that relatively lower preoperative serum TC level was associated with lower recurrence-free survival (P = .040) and CSS (P <.001) rates. Multivariate analysis indicated that in addition to pT stage, M stage, nuclear grade, and Eastern Cooperative Oncology Group Performance Status, serum TC level (hazard ratio, 0.988 per mg/dL; 95% confidence interval, 0.980-0.998; P = .019) was an independent predictor of CSS. CONCLUSION Low preoperative serum TC level is associated with worse prognosis in patients with clear cell RCC. Consideration of preoperative serum TC level might thus provide additional prognostic information for patients with clear cell RCC.

Abstract
An intrascrotal testicular torsion with malignant testicular tumour is extremely rare. We report a case of a 26-year-old male who was diagnosed with testicular torsion by magnetic resonance imaging and with testicular seminoma after orchiectomy. Through this case, we found that if the possibility of testicular torsion remains during the diagnosis of acute scrotum cases, additional examination adding to colour Doppler sonography should be performed. Furthermore, we should be aware of the possibility of testicular tumours during the diagnosis and treatment of acute scrotums. If the affected testis is preserved in the treatment of testicular torsion, a postoperative examination by ultrasound and/or tumour markers for the remaining testis is essential to confirm the absence of testicular tumour.

Abstract
A 76-year-old man presented to our hospital with asymptomatic bleeding of the urethra. Endoscopic examination showed multiple urethral papillary tumors in the pendulous urethra, and the tumors were surgically resected. Histopathological examination indicated urethral condyloma acuminata, and the results of a polymerase chain reaction-based invader assay using urethral swabs taken after surgery suggested low risk human papilloma virus infection. This is a relatively rare case because urethral condyloma acuminata has been reported in only a few elderly patients so far. No obvious recurrence of condyloma acuminata has been observed for 18 months after surgery.

Abstract
Background Emphysematous cystitis (EC) is a comparatively rare urinary tract infection characterized by air within the bladder wall and lumen and is usually associated with immunosuppression or poorly controlled diabetes mellitus. Case presentation We report a case of EC in a 70-year-old man who recently underwent transrectal ultrasound needle-guided prostate biopsy, after which he underwent pylorogastrectomy. He did not have any history of diabetes mellitus or any immunosuppressive disease. The patient developed severe sepsis, requiring intravenous antibiotics and urinary catheterization. Despite therapy, the patient developed disseminated intravascular coagulopathy and acute respiratory distress syndrome. Therefore, he was admitted to the intensive care unit, antibiotic coverage was broadened, and danaparoid sodium and sivelestat sodium hydrate was administered. After 20 days, the patient’s condition improved, and on the 28th day, the patient was discharged to home in a good condition without any sequelae. Conclusion Prompt diagnosis and treatment are warranted to prevent potential morbidity of and mortality in cases of EC.

Abstract
OBJECTIVE To investigate preoperative predictors of ureteral involvement of bladder malignancy and to develop a novel preoperative model for the prediction of ureteral involvement in bladder cancer patients undergoing radical cystectomy. METHODS This study included 197 consecutive bladder cancer patients treated with radical cystectomy. The correlations of preoperative factors with ureteral involvement were analyzed by univariate analysis with Pearson's χ(2-) test and multivariate logistic regression analysis with a stepwise selection procedure. RESULTS Positive ureteral involvement was observed in 38 (19.3%) patients. Tumor location (involvement of the vesical trigone), clinical T stage (≥ cT3) and the number of tumors (≥ 3), but not sex, tumor grade and histological features determined by transurethral resection of bladder tumor, tumor size, shape of tumor, concomitant presence of carcinoma in situ, preoperative intravesical therapy, number of transurethral resection of bladder tumor procedures or the presence of hydronephrosis were significantly associated with ureteral involvement in the univariate analysis. Multivariate logistic regression analysis confirmed that the aforementioned three significant factors identified in the univariate analysis were significant independent predictors of ureteral involvement. The probability of ureteral involvement estimated by a combination of these three parameters was well correlated with the real incidence (R = 0.904, P = 0.0021). CONCLUSIONS Tumor location (involvement of vesical trigone), clinical T stage (≥ cT3) and the number of tumors (≥ 3) are significant independent preoperative predictors of ureteral involvement of malignancy in bladder cancer patients undergoing radical cystectomy. Our predictive model might be useful for preoperative prediction of ureteral tumor involvement.

Abstract
OBJECTIVE Preoperative prognostic factors in bladder cancer patients have not been fully established. This study was undertaken to investigate preoperative prognostic factors, including neutrophil-to-lymphocyte ratio (NLR), and to develop a novel prognostic factors-based risk stratification model for disease-specific survival (DSS) in bladder cancer patients treated with radical cystectomy (RC). METHODS We performed a retrospective analysis of 189 consecutive bladder cancer patients treated with RC at our institution. Prognostic value of the preoperative clinical and laboratory parameters were evaluated by univariate and multivariate Cox proportional hazard model analyses, and patients were stratified according to relative risks (RRs) for DSS. RESULTS One-, 3-, and 5-year DSS rates were 86.8%, 70.8%, and 61.7%, respectively. In univariate analysis, tumor size, clinical T stage, hydronephrosis, concomitance of carcinoma in situ, and some laboratory findings (hemoglobin [Hb] level, platelet count, C-reactive protein, neutrophil count, lymphocyte count, and NLR) were significantly associated with poor prognosis. In multivariate analysis, tumor size, hydronephrosis, Hb level, and NLR were independent factors for predicting poor prognosis. Patients were stratified into 3 risk groups: low (RR = 1.000-3.717), intermediate (RR = 4.149-9.315), and high (RR = 10.397-38.646). The differences among the groups were significant. CONCLUSIONS NLR was an independent prognostic factor, as were tumor size, hydronephrosis, and Hb levels, and the combination of these factors can stratify DSS risks in bladder cancer patients treated with RC. This information may be useful for identifying patients who might be candidates for clinical trials of multimodal treatment strategies, including innovative neoadjuvant treatments.

Abstract
PURPOSE An increase in the pretreatment neutrophil-to-lymphocyte ratio is associated with poor prognosis for various cancers, including renal cell carcinoma. However, the clinical implication of a posttreatment change in the neutrophil-to-lymphocyte ratio in patients with cancer remains unclear. MATERIALS AND METHODS We reviewed the records of 250 patients with nonmetastatic clear cell renal cell carcinoma and analyzed associations among clinicopathological variables, the preoperative and postoperative neutrophil-to-lymphocyte ratio, and recurrence-free survival. RESULTS The 10-year recurrence-free survival rate for patients with a preoperative neutrophil-to-lymphocyte ratio of 2.7 or greater was significantly lower than that for those with a ratio of less than 2.7 (64.4% vs 83.7%, p = 0.0004). When combined with the postoperative ratio, patients with a preoperative ratio of 2.7 or greater could be further divided into 2 groups with a significantly different prognosis. The 10-year recurrence-free survival rate for patients with a preoperative neutrophil-to-lymphocyte ratio of 2.7 or greater and postoperative ratio of less than 2.7 was significantly lower than that for those with a preoperative and postoperative ratio of 2.7 or greater (52.0% vs 83.5%, p = 0.0487). The latter was similar to the 83.7% for patients with a preoperative ratio of less than 2.7. In patients with recurrence the ratio at recurrence was significantly increased compared with the postoperative ratio (mean ± SD 2.82 ± 1.63 vs 2.00 ± 0.90, p = 0.0090). Multivariate analysis showed that tumor size, pathological tumor stage and the neutrophil-to-lymphocyte ratio change (a combination of the preoperative and postoperative ratios) were independent predictors of recurrence. Using these 3 significant variables patients were stratified into low, intermediate and high risk groups, among which the recurrence-free survival rate significantly differed. CONCLUSIONS The posttreatment neutrophil-to-lymphocyte ratio change was a significant prognostic factor for recurrence as well as tumor size and pathological tumor stage in patients with clear cell renal cell carcinoma.
